The station web service (http://service.ncedc.org/fdsnws/station/1) provides access to station metadata in the NCEDC database. The results are returned in XML format using the
FDSN StationXML schema. Users can query for station metadata by network, station, channel, location, time and other search criteria and request results at multiple levels (network, station, channel, response). It can also return information about what time series data are available at the NCEDC.

The resp web service (http://service.ncedc.org/ncedcws/resp/1) provides access
to channel response information in the SEED RESP format (as used by evalresp). Users can query for channel response
by network, station, channel, location and time.
